ABSTRACT The coefficient of variation (COV) of ozone residual is often used to compare the mixing performance of different ozone contacting systems. Multiphase mass transfer CFD modeling is performed and compared with experimental data to investigate the correlation between mass transfer efficiency, a corresponding full cross-sectional spatial COV, a corresponding “grab sample” temporal COV, and a comprehensive uniformity index for mixing for varying sidestream ozone doses. Typical sampling methodology for ozone residual is reviewed and general guidelines for better representative sampling are suggested.

变异系数是表征臭氧应用中混合效率的现实指标吗？

摘要 臭氧残留的变异系数 (COV) 通常用于比较不同臭氧接触系统的混合性能。执行多相传质 CFD 建模并与实验数据进行比较，以研究传质效率、相应的全横截面空间 COV、相应的“抓取样本”时间 COV 以及不同侧流臭氧混合的综合均匀性指数之间的相关性剂量。审查了臭氧残留的典型采样方法，并建议了更好的代表性采样的一般准则。
